3. RESTRUCTURING RESERVE

As previously disclosed, the Company divested its transportation business
effective November 22, 1997.  In conjunction with the divestiture, the Company
recorded during the second quarter a pre-tax restructuring charge of $3,129,000
to cover the costs of exiting the transportation business ($1,443,000) and to
write off certain other non-performing assets, primarily manufacturing
machinery and equipment ($813,000).  At January 31, 1998, $860,000 of the
restructuring charges remained in Current Liabilities.  A summary of the
restructuring activity is presented below (in thousands):

4. NEW ACCOUNTING PRONOUNCEMENTS

The Company adopted Statement of Financial Accounting Standards No. 128,
"Earnings Per Share" during the second quarter of 1998.  The statement
simplifies the standards for computing earnings per share ("EPS") previously
defined in Accounting Principles Board Opinion No. 15, "Earnings Per Share"
(APB 15) and makes them comparable to international EPS standards.  It replaces
the presentation of primary EPS with a presentation of basic EPS.

                 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                 (UNAUDITED)


Basic EPS excludes dilution and is computed by dividing net income available to
common stockholders (numerator) by the weighted-average number of common shares
outstanding (denominator) for the period.  Diluted EPS is computed similarly to
fully diluted EPS under APB 15.  A reconciliation of the numerator and
denominator of the basic EPS computation to the numerator and denominator of
the diluted EPS computation is presented in Exhibit 11 of this document.

In June 1997, SFAS No. 130, "Reporting Comprehensive Income" and SFAS No. 131,
"Disclosures about Segments of an Enterprise and Related Information" were
issued.  SFAS No. 130 establishes standards for the reporting of comprehensive
income and its components in a financial statement presentation.  SFAS No. 130
separates comprehensive income into net income and other comprehensive income,
but does not change the measurement and presentation of net income.  Other
comprehensive income includes certain changes in the equity of the Company
which are currently recognized and presented separately in the Consolidated
Statements of Stockholder's Equity, such as the change in the Translation
Adjustment account.  SFAS No. 130 is effective for the Company beginning in
fiscal 1999.

SFAS No. 131 establishes new standards for the way companies report information
about operating segments and requires that those enterprises report selected
information about operating segments in the interim financial reports issued to
shareholders.  SFAS No. 131 is effective for the Company beginning in fiscal
1999.

5. SUBSEQUENT EVENTS

On March 5, 1998, the Company announced that it had signed a definitive
agreement to purchase the Fuller's Earth absorbent business of American Colloid
Co., a wholly owned subsidiary of Amcol International, for an amount
approximating $14,800,000.  The purchase includes a production plant and
mineral reserves in Mounds, Illinois, and mineral reserves located in Paris,
Tennessee, and Silver Springs, Nevada.  The absorbent business has annual sales
approximating $15,000,000.  The Company intends to finance the acquisition
through a fixed rate private debt placement.  It is anticipated that the
acquisition will be accounted for as a purchase; accordingly, the purchase
price will be allocated to the underlying assets and liabilities based upon
their estimated fair values.  The acquisition is expected to be completed prior
to the end of the third quarter of fiscal 1998.

On March 10, 1998, the Board of Directors of the Company authorized the
repurchase of 342,241 Class B shares from a director of the Company at $15 per
share.  This share repurchase completes the Company's authorizations for
further stock repurchases at this time.

MANAGEMENT DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

SIX MONTHS ENDED JANUARY 31, 1998 COMPARED TO SIX
MONTHS ENDED JANUARY 31, 1997
- -----------------------------

RESULTS OF OPERATIONS
- ---------------------

Total Company net sales for the six months ended January 31, 1998 were
$80,661,000, a decrease of 3.2% from net sales of $83,317,000 in the first six
months of fiscal 1997.  This decrease was primarily due to exiting the
transportation business.  Transportation sales for the first half of fiscal
1997 were $3,867,000 compared to $2,373,000 in the first half of the current
year.  Excluding transportation, sales declined 1.5% in the first half of
fiscal 1998 versus fiscal 1997.  Net income for the first six months of fiscal
1998 was $1,776,000 or $0.28 per share, compared to $4,194,000 or $0.63 per
share earned in the first half of fiscal 1997.  The decrease was primarily due
to a restructuring charge recorded in the second quarter of fiscal 1998.  The
restructuring charge, which covered the costs of exiting the transportation
business and writing off certain non-performing assets, reduced income before
income taxes by $3,129,000, net income by $2,237,000, and earnings per share by
$0.36 for the six months ended January 31, 1998.

Net sales of cat box absorbents decreased $1,440,000, or 2.8% from prior year
amounts, due in part to increased levels of promotional activity by the
Company's competitors and a program by a major customer to reduce on-hand
inventory levels. Net sales of agricultural and fluids purification products
increased $404,000, or 2.1%, from the comparable period in fiscal 1997.  The
higher sales resulted from an increased demand for fluids purification products
in the United Kingdom.  Net sales of industrial and environmental sorbents were
comparable to prior year levels.  Net sales of transportation services
decreased $1,494,000 or 38.6% from the second quarter of fiscal 1997 due to the
exiting from this business in November 1997.

Consolidated gross profit as a percentage of net sales for the six months ended
January 31, 1998 increased to 31.2% from 31.1% in the comparable period of
fiscal 1997.

Operating expenses as a percentage of net sales increased to 27.1% in the first
six months of fiscal 1998 from 23.2% in the same period of fiscal 1997.  This
increase is primarily due to a pre-tax charge of $3,129,000 recorded in the
second quarter of fiscal 1998 for the restructuring reserve.

Interest expense decreased $116,000 and interest income decreased $84,000.

The Company's effective tax rate was 28.5% of pre-tax income in the first half
of both fiscal 1998 and fiscal 1997.

The assets of the Company decreased $1,322,000 during the first half of fiscal
1998.  Current assets increased $1,407,000, or 3.0%, from fiscal 1997 year end
balances primarily due to increased accounts receivable, prepaid expenses, and
inventories, partially offset by lower cash and cash equivalents.  Property,
plant and equipment, net of accumulated depreciation, decreased $1,592,000
during the first half due to the write-off of non-performing assets against the
restructuring reserve and depreciation expense exceeding capital expenditures.

Total liabilities in the six months ended January 31, 1998 increased $926,000,
or 2.5%, due primarily to the restructuring reserve recorded in the second
quarter of this year.  Current liabilities increased $709,000 or 4.5% from July
31, 1997 balances, also due to the restructuring reserve.

EXPECTATIONS
- ------------

The Company anticipates sales during the remainder of fiscal 1998 will be at
about the same level as sales in the comparable period of fiscal 1997 after
taking into account the approximately $2 million per quarter of backhaul
revenue previously generated by the Company's transportation business, which
was divested on November 21, 1997.  Moderately higher sales of cat box
absorbents and fluid purification products should substantially offset the lost
backhaul revenue.  However, sales growth of cat box absorbents is subject to
continuing competition for shelf space in the grocery, mass merchandiser and
club  markets.  Demand for AGSORB carriers and Pure-Flo fluids purification
products are expected to show slight improvement through the remainder of the
fiscal year. Furthermore, the purchase of the Fuller's Earth business of
American Colloid Co. will result in additional sales of cat box absorbents,
agricultural carriers and industrial absorbents after the acquisition is
completed.

The foregoing statements under this heading are "forward looking statements"
within the meaning of that term in the Securities Exchange Act of 1934, as
amended.  Actual results may be lower than those reflected in these
forward-looking statements, due primarily to:  continued vigorous competition
in the grocery, mass merchandiser and club markets; the level of success of new
products; and the cost of new product introductions and promotions in consumer
markets.  These forward-looking statements also involve the risk of changes in
market conditions in the overall economy and, for the agricultural and fluids
purification division, in the planting activity, crop quality and overall
agricultural demand, including export demand.

LIQUIDITY AND CAPITAL RESOURCES
- -------------------------------

The current ratio decreased to 2.9 at January 31, 1998 from 3.0 at July 31,
1997.  Working capital increased $698,000 during the six months ended January
31, 1998 to $31,863,000.  Cash provided by operations continues to be the
Company's primary source of funds to finance investing needs and financing
activities.  During the six months ended January 31, 1998, the balances of
cash, cash equivalents and other investments decreased $3,939,000.  Cash
provided by operating activities of $3,315,000 was used to fund purchases of
the Company's common stock ($3,053,000), capital expenditures ($2,898,000),
principal payments on long term debt ($1,851,000) and pay dividends ($931,000).
Total cash and investment balances held by the Company's foreign subsidiaries
at January 31, 1998 and July 31, 1997 were $3,055,000 and $2,803,000
respectively.

THREE MONTHS ENDED JANUARY 31, 1998 COMPARED TO
THREE MONTHS ENDED JANUARY 31, 1997
- -----------------------------------

Consolidated net sales for the three months ended January 31, 1998 were
$40,912,000, a decrease of $1,880,000 or 4.4%, over net sales of $42,792,000 in
the second quarter of fiscal 1997.  This decline was primarily due to exiting
the transportation business.  Transportation sales for the second quarter of
fiscal 1997 were $1,831,000 compared to $447,000 this year.  Excluding
transportation, sales declined 1.2% in the second quarter of fiscal 1998 versus
fiscal 1997.  Net income for the three months ended January 31, 1998 was
($97,000) or ($0.02) per share, a decrease of 104.3% from $2,264,000, or $0.34
per share, earned in last year's quarter. The decrease was due to a
restructuring charge recorded in the second quarter of fiscal 1998.  The
charge, which covered the costs of exiting the transportation business and
writing off certain non-performing assets, reduced income before income taxes
by $3,129,000, net income by $2,150,000, and earnings per share by $0.36 for
the three months ended January 31, 1998.

Net sales of cat box absorbents decreased $906,000 or 3.4% from prior year
amounts, due in part to increased levels of promotional activity by the
Company's competitors and a program by a major customer to reduce on-hand
inventory levels.  Net sales of agricultural and fluids purification products
increased $470,000, or 4.7% from the comparable period in fiscal 1997.  The
higher sales resulted from increased demand for AGSORB carriers as well as
PURE-FLO Supreme fluids purification products in the United Kingdom.  Net sales
of industrial and environmental sorbents were comparable to last year's second
quarter.

Consolidated gross profit as a percentage of net sales for the three months
ended January 31, 1998 increased to 32.5% from 31.9% in the comparable period
of fiscal 1997.  Changes in sales mix, a Company-wide effort to reduce costs
and exiting the transportation business contributed to this increase.

Operating expenses as a percentage of net sales increased to 31.8% in the
second quarter of fiscal 1998 from 23.6% in the same quarter of the prior year.
This increase is primarily due to the pre-tax restructuring charge of
$3,129,000 recorded in the second quarter of fiscal 1998.

Interest expense decreased $87,000 while interest income decreased $45,000.

The Company's effective tax benefit rate was 17.1% of pre-tax income in the
second quarter of 1998 as compared to the effective tax rate of 28.5% for the
second quarter of fiscal 1997.


FOREIGN OPERATIONS
- ------------------

Net sales by the Company's foreign subsidiaries for the six months ended
January 31, 1998 were $6,481,000, or 8.0% of total Company sales.  This
represents an increase of $361,000 from the same period of fiscal 1997, in
which foreign subsidiary sales were $6,120,000, or 7.3% of total Company sales.
Net income of the foreign subsidiaries for the first six months of fiscal 1998
was $321,000 compared with $431,000 in the same period of fiscal 1997.
Identifiable assets of the Company's foreign subsidiaries as of January 31,
1998, were $11,668,000, an increase of $1,802,000 from $9,866,000 as of July
31, 1997.  The increase is primarily due to higher prepaid expenses,
inventories, and cash and cash equivalents.

Net sales by the Company's foreign subsidiaries for the quarter ended January
31, 1998 were $3,417,000 or 8.4% of total Company sales.  This represents an
increase of $298,000, or 9.6% from the same quarter in fiscal 1997, in which
foreign subsidiary sales were $3,119,000, or 7.3% of total Company sales.  Net
income of the foreign subsidiaries for the second quarter of fiscal 1998 was 
$135,000 compared to $286,000 in the same period of fiscal 1997.

         OIL-DRI ANNOUNCES PLANS TO PURCHASE FULLER'S EARTH BUSINESS
                           FROM AMCOL INTERNATIONAL

CHICAGO -- March 5,1998 -- Oil-Dri Corporation of America (NYSE:ODC)
announced today that it has signed an agreement to purchase the Fuller's
Earth absorbent business of American Colloid Co., a wholly owned subsidiary
of AMCOL International (NASDAQ:ACOL). The business has approximately
$15,000,000 in revenues, including coarse private label cat litter, oil and
grease absorbents and agricultural carriers.

The agreement is subject to approval by each company's Board of Directors.
Closing of the acquisition will be pending normal due diligence.

President and Chief Executive Officer, Daniel S. Jaffee, commented; "With
this acquisition, we will increase cat litter sales to many new customers and
expand our relationships with existing ones. This will give us an opportunity
to provide retailers with a consolidated source for both their private label
and branded cat litter products. Oil-Dri's branded products currently have
ACV distribution of 70% in U.S. grocery and mass merchandiser outlets.

Included in the purchase are a production plant and associated mineral
reserves in Mounds, IL and mineral reserves located in Paris, TN and Silver
Springs, NV.

"This strategic acquisition will increase our manufacturing capacity and
distribution throughout the U.S. with a new midwestern manufacturing facility
and an expanded mineral reserve base in the western United States," said
Daniel Jaffee.

"Cost of the acquisition was less than a dollar for a dollar of sales.
Financing will be a long-term, fixed-rate, private placement. Once the
acquisition is integrated into our manufacturing and distribution system, it
will provide positive cash flow, increased earnings and an improved return on
shareholders' equity."

DELIVERING ON OUR STRATEGIC PLAN
Daniel Jaffee continued, "The acquisition of this business will allow us to
leverage core competencies and market experience in our pet products group
with increased manufacturing flexibility, additional mineral reserves and
more efficient logistical capabilities. It will make Oil-Dri the largest
supplier of private label cat litter in the country and give us the critical
mass needed to participate more competitively in the cat litter market.

"As indicated at our annual shareholders' meeting, we anticipate that
growth in the next five years will come from both internal development and
acquisitions. With this acquisition and the new product launches scheduled
for the fourth quarter of our current fiscal year, fiscal 1999 promises to be
very exciting."

Richard M. Jaffee, Oil-Dri's chairman, also remarked on the acquisition: "Dan
and his team worked together to evaluate all the aspects of this opportunity
and the synergies that it will provide. This is a very positive development
for Oil-Dri. They are to be congratulated on a job well done."

     Real Property, including all mineral rights appertaining thereto, is free
     and clear of any mortgage, deed of trust, liability, claim, security
     interest, lien or encumbrance, other than Permitted Exceptions (as defined
     in Section 5.3 below).  If any of the Real Property is encumbered by a
     mortgage or deed of trust, no notice has been received by Seller from any
     mortgagee or trustee or beneficiary thereunder asserting that a default or
     breach exists thereunder, and, to Seller's knowledge, no default or breach
     exists thereunder and there has not occurred any event which with notice
     or lapse of time or both would constitute such a default or breach.  With
     respect to the Real Property, there are no encroachments or projections of
     improvements located on any other property onto any part of such Real
     Property nor do any improvements located on any part of such Real Property
     encroach or project upon other properties other than Permitted Exceptions
     (as defined in Section 5.3 below).

          (b Except as described in Schedule 3.7(b), there are no pending or,
     to the knowledge of Seller, threatened actions, suits or proceedings,
     including condemnation or similar proceedings, against or affecting the
     Real Property or any material portion thereof, or relating to or arising
     out of the interest of Seller in the Real Property or any material portion
     thereof, in any court or before or by any federal, state, county or
     municipal department, commission, board, bureau, agency, or other
     governmental instrumentality which, if decided contrary to Seller's
     interests, would have an adverse effect on the value or use of the Real
     Property as currently used or reserved for use.  Except as described in
     Schedule 3.7(b), no special assessment is pending or has been proposed
     against any portion of the Real Property.  Except as described in Schedule
     3.7(b), no person or entity is or has been in adverse possession of the
     Real Property or any part thereof for any period of time next preceding
     the Closing Date.

          (c No portion of the Real Property is in violation of, or used or
     occupied in a manner in violation of, any building or fire code, zoning
     ordinance, certificate of occupancy, insurance regulation or any other
     federal, state, county or municipal law, ordinance, order or regulation or
     statute applicable thereto, which violation would have a material adverse
     effect on the value or use of such Real Property as currently used or
     reserved for use.  All of the Real Property used by Seller or reserved for
     use by Seller conforms with the uses permitted by the applicable zoning
     ordinances (without benefit of the prior nonconforming use doctrine) or
     pursuant to an existing permanent variance, permit or exception to such
     ordinance which variance, permit or exception would inure to the benefit
     of Purchaser as owner of the Real Property in all instances where the
     failure to so conform or the failure of such variance, permit or exception
     to inure to the benefit of Purchaser would have an adverse effect on the
     use or value of such Real Property.

          (d To Seller's knowledge, the improvements situated on the Real
     Property which are necessary to operate the Purchased Assets as currently
     conducted by Seller are, in all material respects, structurally sound and
     in good condition, order and repair, taking into account their current
     use, age, ordinary wear and tear and normal maintenance.

          (e Schedule 3.7(e) attached hereto sets forth a true and complete
     list of all unrecorded licenses, leases, use agreements and understandings
     (in each case, whether oral or written) relating to the use or occupancy
     of the Real Property by others.  Except as set forth in Schedule 3.7(e),
     all such licenses, leases, use agreements and understandings are, to the
     knowledge of Seller, in full force and effect in accordance with their
     terms, and neither Seller nor, to the knowledge of Seller, any other party
     thereto is in default with respect to any of its obligations thereunder,
     and to the best knowledge of Seller, there has not occurred any event
     which with notice or the lapse of time or both would constitute such
     default, and all such licenses, leases, use agreements and understandings
     are terminable on not more than six (6) months prior written notice by
     Seller except as otherwise set forth on Schedule 3.7(e).

          (f Except as set forth in Schedule 3.7(f), Seller has unrestricted
     legally enforceable access from the Real Property (including, without
     limitation, any non-owned parcels of Real Estate as to which Seller has
     any patented mineral claims, mineral rights or surface rights) to any
     railroad rights of way, public highways, roads or streets sufficient to
     permit the conduct of the operation of the Purchased Assets as currently
     operated or reserved for operation by Seller, and, to the knowledge of
     Seller, there is no currently existing fact or condition which would
     result in the interference with or termination of such access.

          (g Except as set forth on Schedule 3.7(g), (i) Seller has no
     knowledge that the Real Property has ever been used as a cemetery or
     Native American burial ground; (ii) Seller has not received any written
     notice that there are any endangered or threatened species of animal or
     plant which at any time during the past five (5) years have lived on any
     of the Real Property; (iii) Seller has not received any written notice
     that any portion of the Real Property is a "wetland," as that 

                                  Page -30-

     term is used under any federal law, rule or regulation or any state
     or local law, rule or regulation applicable in the state and locality in
     which the Real Property is situated; and (iv) to the knowledge of Seller,
     no portion of the Real Property has ever been designated as
     archaeologically significant based on findings of Native American
     artifacts or otherwise.

          (h All public utilities required for the present activities of the
     operation of the Mounds Facility connect into the Real Property or are
     available to the Real Property at the boundaries thereof.

          (i No individual, governmental authority, corporation, partnership or
     other entity has any option to purchase, or right of first offer or first
     refusal with respect to, any material portion of the Real Property, or is
     party to any agreement which, under any circumstances, could become such
     an option or right of first offer or first refusal.  Schedule 3.7(i)
     contains a list of all options to purchase or acquire any interest in real
     property, or rights of first offer or first refusal with respect to any
     interest in real property (including any interest which, upon acquisition,
     would be a Leasehold Interest (as defined in Section 3.8 below)), which
     options or rights of first offer or first refusal are held by Seller and
     relate to the Purchased Assets.  With respect to each such option or right
     of first offer or first refusal so listed on Schedule 3.7(i), said
     Schedule includes the legal description of the land as to which there is
     an option or right of first offer or first refusal and a brief description
     of any improvements thereon.

          (j Seller does not own or hold any interest whatsoever in real
     property situated within twenty-five (25) miles of any point on the
     exterior boundaries of any of the Unpatented Mining Claims referred to in
     Section 3.9, any of the Real Property or any of the Leasehold Interests
     except for the Real Property, the Leasehold Interests and the Unpatented
     Mining Claims.

          (k The Real Property, the Leasehold Interests and the Unpatented
     Mining Claims sold or transferred to Purchaser as part of the Mounds
     Assets contain deposits and reserves of porters creek clay (the "Porters
     Creek Clay Reserves") of commercial quality and in quantity sufficient to
     support the operation of the Purchased Assets, in each case consistent
     with Seller's past practice and production rates for the immediately two
     (2) preceding fiscal years, for at least ten (10) years after the Closing
     Date.  Such Porters Creek Clay Reserves consist of buff-colored porters
     creek clay and black and grey-colored porters creek clay, and have Ohaus
     bulk density of 39 to 45 pounds per cubic foot when dried to an eight (8)
     to ten (10) percent free moisture content.

     3.8  LEASEHOLD INTERESTS.

all leases, subleases, rental or other occupancy agreements relating to any
real property and any rights to use or occupy real property, or rights or
interests therein, held by Seller as lessee or sublessee (in each case, whether
recorded or unrecorded) and used or held for use in or relating to the
Purchased Assets other than the Real Property (the "Leasehold Interests").  All
of the Leasehold Interests are in full force and effect in accordance with
their terms and neither Seller, nor, to the knowledge of Seller, any other
party thereto is in default or breach with respect to any of its obligations
thereunder and, to the knowledge of Seller, there has not occurred any event
which, with notice or lapse of time or both, would constitute such default or
breach.  Seller has not received any written notice that there are any
underlying mortgages or deeds of trust affecting any leased real property and
having priority over the Leasehold Interest, or rights or interests therein,
used by Seller.  Seller is in full use or possession of the real property
subject to the Leasehold Interests, or rights or interests granted therein. 
Seller is not using any real property or interest therein subject to a
Leasehold Interest in violation in any material respect of any law, regulation,
code, ordinance or decree or other legal requirement.  The representations and
warranties contained in Sections 3.7(b), (f), (g) and (h) shall be deemed to
apply to any real property, or interest granted therein, which is the subject
of a Leasehold Interest.

</TABLE>

          (b With respect to the Unpatented Mining Claims, subject only to the
     paramount title of the United States:  (i) the Unpatented Mining Claims
     were laid out and monumented consistent with industry practices on federal
     lands which were open to entry under the Mining Law of 1872 at the time of
     location; (ii) location notices and certificates were properly recorded
     and filed with appropriate governmental authorities; (iii) affidavits of
     assessment work, notices of intent to hold, or verified reports were
     timely and duly recorded and filed with appropriate agencies for each of
     the Unpatented Mining Claims for each year for all assessment years during
     which the performance of assessment work was required by law and in which

                                  Page -31-



<PAGE>   16
     such affidavit, notice or report was required to be filed, and payments of
     rental fees or maintenance fees in lieu of assessment work were timely
     paid for each assessment year when such payments were required by law;
     (iv) the work and expenditures described in said affidavits, notices and
     reports were in fact made and performed in a good faith effort to satisfy
     assessment work requirements; (v) the Unpatented Mining Claims are free
     and clear of liens, production royalties, advance royalties, rents,
     bonuses or bonus payments or finder's fees in favor of any party; (vi)
     Seller has no knowledge of material conflicting claims or activities or
     possession by third parties in anticipation of such claims, except as set
     forth in Schedule 3.9(b); and (vii) Seller has located each such
     Unpatented Mining Claim in the good faith expectation of discovering
     valuable minerals.

          (c Where Seller's ownership of the Unpatented Mining Claims does not
     give Seller surface rights of ingress and egress and use of the surface of
     such mining claims for mining and related purposes, Seller has valid and
     enforceable agreements with the owners of such surface rights permitting
     Seller access to such claims for mining and related purposes, all of which
     agreements are set forth in Schedule 3.9(c).  Seller is not in default
     with respect to any of its obligations thereunder and, to Seller's best
     knowledge, there has not occurred any event which, with notice or lapse of
     time or both, would constitute such default.  The agreements set forth in
     Schedule 3.9(c) are fully assignable and by their terms do not require
     compensation to the surface owner.

          (d With respect to any Real Property constituting part of the
     Purchased Assets, all water rights of Seller appurtenant to such Real
     Property are set forth in Schedule 3.9(d), and such water rights, if any,
     have been granted pursuant to the agreements, applications to appropriate
     water, certificates of appropriation and applications to change water
     rights set forth in Schedule 3.9(d).  Seller is not in default with
     respect to any of its obligations under such agreements and, to the best
     knowledge of Seller, there has not occurred any event which, with notice
     or lapse of time or both, would constitute such default.  The agreements
     set forth in Schedule 3.9(d), if any, are fully assignable to Purchaser
     and by their terms do not require compensation to any party thereto.

     3.10 PERSONAL PROPERTY AND TITLE TO ASSETS, ETC.

          (a Schedule 3.10(a) attached hereto sets forth a true and complete
     list and brief description from Seller's business records as of the date

          (b Except as set forth in Schedule 3.10(b) attached hereto, at the
     Closing, all of the Purchased Assets constituting personal property
     including, but not limited to, such assets described in any Disclosure
     Schedule (as defined in Section 3.28 below) will be free and clear of any

     third parties of any kind other than liens and encumbrances for taxes and
     charges not yet due and leased equipment and machinery (collectively, the

     repair, taking into account ordinary wear and tear.

     3.11 INVENTORIES.

     excess inventory, included in the Purchased Assets will be in salable
     condition on the Closing Date and will be located at an owned or leased
     location included in the Purchase Assets or in transit thereto.  All
     work-in-process inventories, net of reserves for obsolete and excess

     capable of being processed or made into salable condition in the ordinary
     course of business and will be located at an owned or leased location

     Assets and all such packaging materials, purchased raw materials and fuels
     are in usable condition.  For purposes of this Section 3.11, inventories
     of any finished products shall not be considered salable if they do not
     meet a customer's specifications or if they exceed the respective
     quantities of such finished products (by grade) that were sold in the
     three (3) months ending February 28, 1998, and inventories of any
     packaging materials, purchased raw materials and fuels shall not be
     considered usable if they exceed the respective quantities of such

          (b At Closing, the value of inventory constituting salable finished
     products delivered to Purchaser at the Mounds Facility shall be at least
     equal to Nine Hundred Eleven Thousand Dollars ($911,000).  Such inventory
     shall be valued at the lower of cost (on a last-in, first-out basis) or
     net realizable value (which is the estimated selling price less selling
     and distribution expenses).

     collective bargaining and the payment of social security and other taxes. 
     Seller has no material labor relations problems at the Mounds Facility,
     and there has been no union organization efforts by the employees of
     Seller at the Mounds Facility.

          (c   With respect to employees of Seller located at the Paris Facility
     and the Nevada Facility, Seller is not required to comply with the Worker
     Adjustment Retraining and Notification Act, as amended (the "WARN Act"),
     and applicable state plant closing laws based upon the assumption that any
     permanent layoffs of such employees will not constitute "plant closings"
     or "mass layoffs" as those terms are defined in the WARN Act.

     3.19 EMPLOYEE BENEFIT PLANS.  Schedule 3.19  contains a list of all
current employee benefit plans, within the meaning of Section 3(3) of the
Employee Retirement Income Security Act of 1974, as amended ("ERISA"), whether
formal or informal, available to any current or former employee, officer or
director of the Mounds Facility (collectively, the "Benefit Plans").   Each
Benefit Plan is and has been in compliance in all material respects with, and
each such Plan is and has been operated in accordance with, the documents
governing them and the applicable laws, rules and regulations, including,
without limitation, the rules and regulations promulgated by the
Department of Labor, the Pension Benefit Guaranty Corporation and the Internal
Revenue Service ("IRS") under ERISA, the Code or any other applicable law.

     3.20 INSURANCE.  Schedule 3.20 lists and briefly describes each insurance
policy maintained by Seller (and the insured values thereof) with respect to
the Mounds Assets.  All of such insurance policies are in full force and
effect.

     3.21 AFFILIATED TRANSACTIONS.  No officer, director, shareholder or
affiliate of Seller or any Person related by blood or marriage to any such
Person or any entity in which any such Person owns any beneficial interest, is
a party to any agreement, contract, commitment or transaction with Seller
related to the Purchased Assets or has any interest in the Purchased Assets.

     3.22 COMPLIANCE WITH LAWS; PERMITS; CERTAIN OPERATIONS.

          (a   Seller is in compliance in all material respects with all
     applicable laws and regulations of foreign, federal, state and local
     governments and all agencies thereof which affect the Purchased Assets,
     and no claims are currently pending against Seller alleging a violation of
     any such law or regulation.  In particular, but without limiting the
     generality of the foregoing, Seller is not in violation of, nor has Seller
     received a notice or charge asserting any violation of, the Immigration
     Reform and Control Act of 1986, the Mine Safety and Health Act of 1977, as
     amended; any Environmental Laws; or any other state or federal acts
     (including rules and regulations thereunder) regulating or otherwise
     affecting the employment of aliens or reclamation, in each case with
     respect to the Purchased Assets.  Seller has also complied and is in
     substantial compliance with all legally required reclamation plans or any
     reclamation activities undertaken by Seller, and true and correct copies
     of all such reclamation plans and a report on the status of each is set
     forth on Schedule 3.22.

          (b   To the knowledge of Seller, Seller holds all Permits,
     certifications and other authorizations of foreign, federal, state and
     local governmental agencies required for the ownership, mining and
     operation of the Purchased Assets.  To the extent assignments or transfers
     are permitted thereunder, such Permits, licenses and certifications and
     other authorizations are being sold or transferred to Purchaser as part of
     the Purchased Assets.  To the extent any of such Permits, certifications
     and other authorizations cannot be transferred to Purchaser prior to
     Closing, Seller has no reason to believe that Purchaser will not be able
     to effectuate the transfer thereof to Purchaser or receive an equivalent
     Permit, certification or other authorization, in each case without
     incurring cost therefor other than ordinary and customary federal, state,
     local and municipal transfer and filing fees.

after the date hereof (but in no event later than fifteen (15) business days),
at Seller's own expense, the following:

          (a) commitments for title insurance ("Title Commitments") committing
     to insure Purchaser's title in the Real Property listed on Schedule 3.7(a)
     (other than the Real Property at the Nevada Facility), including, without
     limitation, minerals and mineral rights, in an amount equal to the fair
     value thereof, which Title Commitments shall be for ALTA Form Owner's
     Policies containing extended coverage, zoning 3.1 with parking,
     contiguity, location and access endorsements and shall deliver proforma
     title insurance policies on the Closing Date;

          (b) surveys of all the Real Property referred to in subsection (a)
     above (other than the Real Property at the Nevada Facility), dated within
     3 months of the date of this Agreement, certified by licensed surveyors
     conforming to ALTA standards and disclosing the location of all
     improvements, easements, party walls, sidewalks, roadways, utility lines
     and access to public streets and roads (the "Surveys"), which Surveys
     shall disclose the location of the improvements thereon to be within the
     lot lines, the location of the buildings to be within all building and
     setback lines, no encroachments of buildings or other improvements from
     adjoining properties or other survey defects;

          (c) surveys of all the Real Property at the Nevada Facility prepared
     by Seller, which Seller hereby represents and warrants are true and
     correct in all material respects; and

          (d) UCC search reports ("UCC Searches") of Seller disclosing no liens
     or encumbrances against the Purchased Assets.

     Within ten (10) business days of the date that Seller shall have delivered
all of the Title Commitments and Surveys to Purchaser hereunder, Purchaser
shall deliver to Seller, in writing, such objections as Purchaser may have to
anything reflected, contained, determined or set forth therein which affects
the marketability of the Real Property or which would prevent Purchaser from
using the Real Property in the manner currently used in the operation of the
Purchased Assets.  For purposes of this Agreement, marketable title shall be
determined in accordance with applicable title standards adopted in the state
in which the Real Property is located.  Any such title or survey matters as to
a particular portion of Real Property to which Purchaser does not object within
such time period shall be deemed to be Permitted Exceptions hereunder as to
such portion of Real Property (all of such matters referred to herein as
"Permitted Exceptions").  If exceptions to the title to the Real Property are
contained in the Title Commitments or any Schedule to this Agreement, or if
exceptions appear from the Surveys, and if in either case Purchaser delivers
written objections thereto in accordance with this Section 5.3, then Seller
shall have a period of thirty (30) days within which to (i) cure, remove or
insure over such exceptions to the reasonable satisfaction of Purchaser or (ii)
provide Purchaser with notice that it is unable to cure, remove or insure over
such exceptions.  Seller shall in good faith use reasonable efforts to
eliminate or cure all title or survey defects to which Purchaser objects in
accordance with this Section 5.3; provided, however, that Seller shall not be
required to commence or maintain any lawsuit or expend any amount in excess of
(A) $50,000 with respect to the Real Property related to the Mounds Assets and
(B) $40,000 in the aggregate with respect to the Real Property related to the
Paris Assets and the Nevada Assets, in each case to cure or remove such
exceptions.  If Seller is unable to cure, remove or insure over the exceptions
within such thirty (30) day period or if Seller provides written notice to such
effect to Purchaser, then by written notice to Seller within ten (10) days
after the earlier of the expiration of such thirty (30) day period or
Purchaser's receipt of Seller's notice to such effect, Purchaser shall have the
right, as Purchaser's sole remedy hereunder, to (A) waive its objections and
accept title subject to the exceptions without set-off or reduction in the
Purchase Price or (B) to terminate this Agreement.

     5.4 DUE DILIGENCE AND CONFIDENTIALITY.

         (a) Due Diligence.  Purchaser will initiate a pre-acquisition due
diligence investigation and review of the books, records and facilities of the
Purchased Assets and will complete such pre-acquisition due diligence
investigation not later than forty-five (45) days following the date of this
Agreement (such 45th day following the date of this Agreement or such earlier
date that Purchaser notifies Seller in writing that it has completed its due
diligence investigation is referred to herein as the "Review Date").
Seller agrees to provide access to information for purposes of such
pre-acquisition due diligence investigation in accordance with Section 5.1(f)
hereof.  Purchaser shall advise Seller as promptly as practicable at the
conclusion of such pre-acquisition due diligence investigation of all matters
then known to Purchaser which Purchaser shall in good faith determine (i) to be
inconsistent in any material and adverse respect with any of the
representations and warranties of Seller contained in this Agreement, or (ii)
to deviate materially and adversely from Seller's Latest Balance Sheet.
Purchaser shall have the right to terminate this Agreement as set forth in
Section 10.1(c) based upon such due diligence investigation.

         (b) Confidentiality.  The parties hereto agree that all information
received from another party or any subsidiary thereof in connection with the
transactions contemplated herein shall be confidential.  Neither such party nor
any of their respective 

                                  Page -40-



<PAGE>   25
agents, employees, accountants, attorneys or other representatives shall
divulge any confidential information relating to the business of Purchaser or
Seller to a third party or use the same in any manner for the profit or to the
benefit of Purchaser or Seller, or any such employee, agent or a third party. 
In the event this Agreement is terminated, each such party shall return to the
other its confidential information without retaining any notes or abstracts
therefrom.  The obligation of the parties to keep information confidential
shall not apply to (i) any information which (A) was already lawfully in its
possession prior the disclosure thereof by Purchaser or Seller; (B) was then
generally known to the public other than as a result of a breach of this
confidentiality obligation; (C) became known to the public through no fault of
the parties or any of their respective agents or representatives; or (D) was
lawfully disclosed to the parties by a third party who was not bound by any
obligation of confidentiality to the parties, or (ii) disclosures required to
be made to third parties in accordance with this Agreement, any law, regulation
or order of a court or regulatory agency of competent jurisdiction or authority
or information included in regulatory or supervisory filings.  The provisions
of this Section 5.4(b) shall survive the termination or expiration of this
Agreement for two (2) years; provided, however, such obligations shall not
apply to Purchaser with respect to the Purchased Assets after the Closing Date.

by Seller to Purchaser of any contract, commitment, license, lease or other
agreement of Seller representing a Contract Right is not permitted or is not
permitted without the consent of any other party thereto (the "Nonassignable
Contracts"), this Agreement shall not be deemed to constitute an assignment of
any such Nonassignable Contract if such consent is not given or if such
assignment otherwise would constitute a breach of, or cause a loss of
contractual benefits under, any such Nonassignable Contract, and Purchaser
shall assume no obligations or liabilities thereunder.  Seller will, prior to
the Closing Date, use its best efforts (subject to the last sentence of Section
11.8 below)  to obtain the consent of the other party to the assignment to
Purchaser of any Nonassignable Contract or any Contract Right.  Seller shall
advise Purchaser promptly in writing with respect to any Nonassignable Contract
with respect to which it knows or has reason to believe it shall not receive
any required consent.  Without in any way limiting Seller's obligation to
obtain all consents and waivers necessary for the sale, transfer, assignment
and delivery of the Nonassignable Contracts and the Purchased Assets to
Purchaser hereunder or 

                                  Page -44-

Purchaser's rights under Section 6.1(e) hereof, if any  such consent is not
obtained or if such assignment is not permitted irrespective of consent and the
Closing hereunder is consummated, Seller shall cooperate with Purchaser in any
reasonable arrangement designed to provide Purchaser with the rights and
benefits, subject to the obligations, under the Nonassignable Contracts,
including enforcement for the benefit of Purchaser of any and all rights of
Seller against any other Person arising out of breach or cancellation by such
other Person and if requested by Purchaser, acting as an agent on behalf of
Purchaser or as Purchaser shall otherwise reasonably require, in each case at
Purchaser's cost.

     8.5  MINING CLAIMS AND SURFACE RIGHTS.

          (a) Seller shall transfer to Purchaser all Permits, licenses and
     governmental approvals of plans of operations on the mining claims or
     related to the water rights included within the Purchased Assets, in each
     case solely to the extent that such Permits, licenses and approvals are
     transferable or assignable without the consent of the governmental
     authority.  Subject to the foregoing, Purchaser shall be responsible for
     obtaining any Permits, licenses, approvals or authorizations which are not
     transferable and as may be necessary or desirable in connection with the
     operation of the Purchased Assets following Closing.

          (b) Seller shall be permitted entry rights of ingress and egress to
     the Purchased Assets at the Paris Facility and the Nevada Facility to
     permit compliance with reclamation plans to the extent such entry does not
     interfere with Purchaser's mineral or related activities at such
     facilities.

     8.6  POSSESSION.  Simultaneously with the Closing, Seller shall take such
steps as are necessary or desirable to put Purchaser in actual possession and
operating control of the Purchased Assets, which, in the case of all tangible
assets, shall be in the same condition in which they were in on the Review Date
as defined in Section 5.4 above), ordinary wear and tear excepted.

     8.7  POST-CLOSING MATERS REGARDING INTELLECTUAL PROPERTY.  Seller agrees
that, from and after the Closing Date, Seller will no longer use or have the
right to use that portion of the Intellectual Property constituting trademarks,
trade names, patents, copyrights, trade dress and other names, marks and
slogans (whether registered, common law or applied for), except for the
Licensed Intellectual Property for the purposes contemplated hereby.

     8.8  PRORATION OF TAXES AND CERTAIN CHARGES.

          (a) All real property Taxes, personal property Taxes or similar ad
     valorem obligations levied with respect to any Real Property included
     within the Purchased Assets for any taxable period which includes the day
     after the Closing Date and ends after the Closing Date, whether imposed or
     assessed before or after the Closing Date, shall be prorated between
     Seller and Purchaser on a daily basis based upon the number of days in the
     taxable period preceding and following the Closing Date.  If any Taxes
     subject to proration are paid by one party, the proportionate amount of
     such Taxes paid (or in the event a refund of any portion of such Taxes
     previously paid is received, such refund) shall be paid promptly by (or
     to) the other party after the payment of such Taxes (or promptly following
     the receipt of any such refund).

<PAGE>   30
          (b) All installments of special assessments or other charges on or
     with respect to any Real Property included within the Purchased Assets
     (including the Real Property) payable by Seller for any period in which
     the Closing Date shall occur, including, without limitation, base rent,
     common area maintenance, percentage or other additional rent, royalties,
     all municipal, utility or authority charges for water, sewer, electric or
     gas charges, garbage or waste removal and cost of fuel, shall be
     apportioned as of the Closing Date based upon meter readings taken on such
     date or, if such charges or rates are assessed either based upon time or
     for a specified period, such charges or rates shall be allocated on a
     daily basis to the periods before and after the Closing  Date, and each
     party shall pay its proportionate share promptly upon the receipt of any
     bill, statement or other charge with respect thereto.

          (c) All installments of base rent, additional rent, license fees or
     other use-related revenue receivable by Seller to the extent attributable
     to the Purchase Assets for any period in which the Closing Date shall
     occur shall be prorated so that Seller shall be entitled to that portion
     of any such installment applicable to the period up to but not including
     the Closing Date and Purchaser shall be entitled to that portion of any
     such installment applicable to any period from and after the Closing Date.

                                  ARTICLE 9

                               INDEMNIFICATION

     9.1  INDEMNIFICATION BY SELLER AND PARENT.  Each of Seller and Parent agree
to jointly and severally indemnify Purchaser and its present and future
officers, directors, employees, agents, affiliates and stockholders
(collectively, the "Purchaser Indemnified Parties") and hold them harmless
against any loss, liability, deficiency, damage, expense, fine, penalty or cost
(including reasonable legal fees and expenses) (collectively, "Losses"), which
Purchaser Indemnified Parties may suffer, sustain or become subject to, as a
result of, relating to or arising out of the following:  (a) any
misrepresentation in any of the representations or breach of any of the
warranties of Seller contained in this Agreement or the Disclosure Schedules
hereto; (b) any breach of, or failure to perform, any agreement or covenant of
Seller contained in this Agreement; (c) any of the Retained Liabilities; (d)
any violation or alleged violation of any Environmental Law or any Release of
Hazardous Materials on, upon or from any real estate owned, leased or operated
by Seller in connection with the Purchased Assets or the operation of the
business related to the Purchased Assets on or prior to the Closing Date; or
(e) any Third Person Claims (as defined in Section 9.3(a) hereof) or threatened
Claims against Purchaser arising out of the actions or inactions of Seller
prior to the Closing with respect to the Purchased Assets or the operation of
the business related to the Purchased Assets prior to the Closing
(collectively, "Purchaser Losses").

     9.2  INDEMNIFICATION BY PURCHASER.  Purchaser agrees to indemnify Seller
and Parent and their respective present and future officers, directors,
employees, agents, affiliates and stockholders (collectively, the "Seller
Indemnified Parties") and hold them harmless against any Losses which Seller
Indemnified Parties may suffer, sustain or become subject to as a result of (a)
any misrepresentation in any of the representations or breaches of any of the
warranties of Purchaser contained in this Agreement; (b) any breach of, or
failure to perform, any agreement or covenant of Purchaser contained in this
Agreement; (c) any of the Assumed Liabilities; (d) any violation or alleged
violation of any Environmental Law or any Release of Hazardous Materials on,
upon or from any real estate owned, leased or operated by Purchaser in
connection with the operation of the Purchased Assets after the Closing Date;
or (e) any Third Party Claims or threatened Claims against Seller arising out
of actions or inactions of Purchaser occurring after the Closing, but only to
the extent such Losses do not constitute Retained Liabilities (collectively,
"Seller Losses").

     9.3  METHOD OF ASSERTING CLAIMS.  As used herein, an "Indemnified Party"
shall refer to "Purchaser Indemnified Parties" or "Seller Indemnified Parties,"
as applicable; the "Notifying Party" shall refer to the party hereto whose
Indemnified Parties are entitled to indemnification hereunder; and the
"Indemnifying Party" shall refer to the party hereto obligated to indemnify
such Notifying Party's Indemnified Parties.

          (a) Promptly after any Indemnified Party has received notice of or
     has knowledge of any claim by a Person not a party to this Agreement
     ("Third Person") or the commencement of any action or proceeding by a
     Third Person (collectively, a "Third Person Claim"),  the Indemnified
     Party shall, if a claim with respect thereto is to be made against any
     Indemnifying Party, give the Indemnifying Party written notice of such
     Third Person Claim. Such notice shall state the nature and basis of such
     Third Person Claim and, if ascertainable, the amount thereof.  In each
     such case the Indemnified Party agrees to give such notice to the
     Indemnifying Party promptly; provided, however, that the failure of the
     Indemnified Party to give such notice shall not excuse the Indemnifying
     Party's obligation to indemnify except to the extent the Indemnifying
     Party has suffered damage or prejudice by reason of the Indemnified
     Party's failure to give or delay in giving such notice.  The Indemnifying
     Party shall have ten (10) business days after receipt of such notice from
     the Indemnified Party to notify the Indemnified Party that it
     acknowledges its obligation to indemnify in respect of such Third Person
     Claim and whether it elects to conduct and control any legal or
     administrative action or suit with respect to a Third Person Claim (the
     "Election Notice").  If the Indemnifying Party does not give the Election
     Notice, the Indemnified Party shall have the right to defend, contest,
     settle, or compromise such action or suit in the exercise of its exclusive
     discretion, at the expense of the 

                                  Page -46-



<PAGE>   31
     Indemnifying Party.  If the Indemnifying Party gives the Election
     Notice, the Indemnifying Party shall have the right to settle, compromise,
     undertake, conduct and control, through counsel of its own choosing and at
     its sole expense, the conduct and defense of such action or suit, and the
     Indemnified Party shall reasonably cooperate with the Indemnifying Party
     in connection therewith (at the expense of the Indemnifying Party);
     provided, however, that (i) the Indemnifying Party shall not thereby
     consent to the imposition of any injunction against the Indemnified Party
     without the written consent of the Indemnified Party; (ii) the
     Indemnifying Party shall permit the Indemnified Party to participate in
     such conduct or settlement through counsel chosen by the Indemnified
     Party, but the fees and expenses of such counsel shall be borne by the
     Indemnified Party except as provided in clause (iii) below; and (iii) upon
     a final determination of such action or suit, the Indemnifying Party shall
     promptly reimburse the Indemnified Party for the full amount of any Losses
     resulting from such action or suit and all reasonable expenses related to
     such Losses incurred by the Indemnified Party, except fees and expenses of
     counsel for  the Indemnified Party incurred after the assumption of the
     conduct and control of such action or suit by the Indemnifying Party.  So
     long as the Indemnifying Party is contesting any such action or suit in
     good faith, the Indemnified Party shall not pay or settle any such action
     or suit.  Notwithstanding the foregoing, the Indemnified Party shall have
     the right to pay or settle any such action or suit, provided that in such
     event the Indemnified Party shall waive any right to indemnity therefor by
     the Indemnifying Party and no amount in respect thereof shall be claimed
     as Losses under this Article 9.  At any time after notice of any Third
     Person Claim, the Indemnifying Party may request the Indemnified Party to
     agree in writing to the payment or compromise of the Third Person Claim,
     whereupon such action shall be taken unless the Indemnified Party
     determines that the contest should be continued, and so notifies the
     Indemnifying Party in writing within fifteen (15) days of such request
     from the Indemnifying Party.  In the event that the Indemnified Party
     determines that the contest should be continued, the Indemnifying Party
     shall be liable pursuant to this Section 9.3(a) with respect to such claim
     only to the extent of the lesser of (A) the amount which the other party
     to the contested Third Person Claim had agreed to accept in complete
     payment or compromise as of the time the Indemnifying Party made its
     request therefor to the Indemnified Party plus other Losses incurred to
     such date with respect to such claim, or (B) such amount for which the
     Indemnifying Party may be liable with respect to such Third Person Claim
     by reason of the provisions of this Section 9.3(a).

          (b) If an Indemnified Party shall have any claim (whether or not a
     Third Person Claim) pursuant to this Section 9.3, including, but not
     limited to, a claim for Losses as the result of the Indemnifying Party's
     failure to acknowledge its obligation to indemnify, the Indemnified Party
     shall deliver to the Indemnifying Party written notice explaining the
     nature and amount of such claim promptly after the Indemnified Party shall
     know the amount of such claim.  The Indemnified Party and Indemnifying
     Party shall thereafter attempt in good faith for a period of not less than
     thirty (30) days to agree upon whether the Indemnified Party is entitled
     to be indemnified and held harmless under this Section 9.3 and the extent
     to which it is entitled to be indemnified and held harmless hereunder.  If
     the parties cannot so agree within said period, the Indemnified Party may
     thereafter commence litigation in a court of competent jurisdiction for a
     determination of its claim.  Upon resolution of any claim pursuant to this
     Section 9.3, whether by agreement between the parties or the rendering of
     a final judgment in any litigation, the Indemnifying Party shall within
     ten (10) of such resolution pay over and deliver to the Indemnified Party
     funds in the amount of any claim as resolved, and any reasonably
     documented fees, including reasonable attorneys' fees, incurred by the
     Indemnified Party with respect to any such litigation.

     9.4  LIMITATION ON CLAIMS.  Notwithstanding anything to the contrary
contained in this Agreement, no indemnification for the breach of a
representation or warranty shall be required under this Article 9 with respect
to any Indemnifying Party until the aggregate amount of all Losses claimed for
indemnification hereunder against such party exceeds Two Hundred Fifty Thousand
Dollars ($250,000) (the "Basket Amount"), and then the Indemnifying Party shall
promptly reimburse the Indemnified Party for the entire Basket Amount (in
excess of One Hundred Thousand Dollars ($100,000)) and all other Losses.  An
Indemnified Party claiming indemnification for Losses with respect to defects
in title (or other claims covered by applicable title insurance) of any Real
Property shall first make reasonable efforts to recover such Losses under
applicable title insurance policies; provided, however, that the failure to so
recover under such title insurance policies shall not limit any of such
Indemnified Party's rights to indemnification hereunder.

     9.5  INDEMNIFICATION PAYMENTS ON AFTER-TAX BASIS.  Any indemnification 
payment hereunder with respect to any Purchaser Losses or Seller Losses, as the
case may be, shall be an amount which is sufficient to compensate the
Indemnified Party for the amount of such Losses, after taking into account all
readily ascertainable increases in federal, state, local, foreign, or other
taxes payable by the Indemnified Party as a result of the receipt of such
payment (by reason of such payment being included in income, resulting in a
reduction of tax basis, or otherwise increasing taxes payable by the
Indemnified Party or the stockholders of Seller, as the case may be, at any
time).  Furthermore, in computing the amount due to a party by reason of a
claim for Losses under this Article 9, the aggregate amount due such party
shall be reduced by (a) the proceeds of any related insurance or recoveries
which cover such claim and are actually received by such party and (b) any 
readily ascertainable resultant income tax benefits inuring to such party.

     9.6 SURVIVAL.  The representations, warranties, covenants and agreements
set forth in this Agreement or in any writing delivered to Purchaser or Seller
in connection with this Agreement shall survive the Closing Date and the
consummation of the transactions contemplated hereby for a period of eighteen
(18) months; provided, however, the representations and warranties contained in
Sections 3.3 (Authorization), 3.12 (Tax Matters), 3.19 (Employee Benefit Plans)
and 3.23 (Environmental) shall survive the Closing Date until the expiration of
their respective statute of limitations (or in the case of Section 3.23, 10
years, whichever is 

                                  Page -47-



<PAGE>   32
shorter); provided, further, however, that to the extent a claim is made
in writing prior to any such expiration with respect to any breach of a
representation, warranty, covenant or agreement, the survival periods set forth
above shall be extended until such claim is finally determined or settled. 
Notwithstanding anything to the contrary in this Agreement, no investigation by
Purchaser shall affect the representations and warranties of Seller under this
Agreement or contained in any document, certificate or other writing furnished
or to be furnished to Purchaser in connection with the transactions
contemplated hereby.  No representations or warranties of a party shall be
deemed to have been breached by the happening of any event or the existence of
any state of facts as to which the party asserting such breach had actual
knowledge at or prior to Closing.  In the event that a party shall determine
prior to Closing that any representations or warranties set forth herein are
incorrect in any material respect, except as set forth in Section 10.2 below,
such party's sole remedy hereunder shall be to terminate this Agreement
pursuant to Section 10.1(b) below.

                                 ARTICLE 10

                                 TERMINATION

     10.1 TERMINATION.  This Agreement may be terminated at any time prior to 
the Closing:

          (a) by mutual consent of Purchaser and Seller;

          (b) by either Purchaser or Seller (i) if there has been a material
     misrepresentation or material breach of warranty or material breach of
     covenant on the part of the other party in the representations and
     warranties or covenants set forth in this Agreement and any such
     misrepresentation or breach, if capable of cure, is not cured within
     fifteen (15) days after written notice thereof to such other party, or
     (ii) if events have occurred which have made it impossible to satisfy a
     condition precedent to the terminating party's obligations to consummate
     the transactions contemplated hereby (other than as a result of any
     willful act or omission by the terminating party);

          (c) by Purchaser, in the event that either (i) Purchaser's
     pre-Closing due diligence investigation and review of the Purchased Assets
     (as described in Section 5.1(f) and Section 5.4 of this Agreement), or
     (ii) any Disclosure Schedule, or any supplement or amendment thereto,
     whenever provided pursuant to Section 3.28 hereof, discloses matters
     (collectively, "Adverse Matters") which (A) are inconsistent in any
     material respect with any of the representations and warranties of Seller
     contained in this Agreement (prior to giving effect to such Disclosure
     Schedule or any supplement or amendment thereto), or (B) deviate
     materially and adversely from Seller's Latest Balance Sheet, by giving
     written notice of termination to Seller within ten (10) days of the Review
     Date or twenty (20) days after the receipt of all such Seller Disclosure
     Schedules or any amendment or supplement thereto.  It is understood and
     agreed that Purchaser shall be entitled to terminate this Agreement under
     this Section 10.1(c) based on clause (B) above if and only if:

               (1) Purchaser determines that any one or more Adverse Matters
          (I) could potentially adversely affect the value of the Purchased
          Assets to be acquired hereunder by an amount, and/or (II) constitute
          liabilities of any nature not disclosed on Seller's Latest Balance
          Sheet, whether actual or contingent, having a potential financial
          impact or cost, equal to or greater than $500,000 in the aggregate
          (such amount and/or cost is hereafter referred to as the "Adverse
          Matters Cost"); or

               (2) Purchaser determines that such potential Adverse Matters
          Cost is an amount greater than $100,000 but less than $500,000 in the
          aggregate and within five (5) days after demand therefor by
          Purchaser, Seller fails to agree to reduce the Purchase Price in an
          amount equal to the difference between such Adverse Matters Cost and
          $100,000 (it being understood and agreed that so long as Seller shall
          agree to such reduction in Purchase Price, Purchaser shall have no
          option to terminate this Agreement under the terms of this Section
          10.1(c)); or

          (d) by either Purchaser or Seller if the transactions contemplated
     hereby have not been consummated by May 15, 1998; provided that neither
     Purchaser nor Seller shall be entitled to terminate this Agreement
     pursuant to this Section 10.1(d) if Purchaser's or Seller's willful
     breach of this Agreement, respectively, has prevented the consummation of
     the transactions contemplated hereby.

     10.2 EFFECT OF TERMINATION.  In the event of termination under Section
10.1, neither Parent, Seller nor Purchaser shall have any further liability or
obligation hereunder to the other or to any stockholder, officer, director,
employee, agent or representative of such other party, but termination of this
Agreement under Section 10.1(b) or Section 10.1(d) shall be without prejudice
to any rights or remedies the non-terminating party may have arising out of any
prior willful breach or willful default of any material representation,
warranty, covenant or condition in this Agreement.

     10.3 EFFECT OF CLOSING.  Seller and Purchaser shall be deemed to have
waived their respective rights to terminate this Agreement upon the completion
of the Closing.

                                 ARTICLE 11

                            ADDITIONAL AGREEMENTS

     11.1 PRESS RELEASE AND ANNOUNCEMENTS.  Prior to Closing, Purchaser and
Seller shall coordinate all publicity relating to the transactions contemplated
by this Agreement and, except as otherwise required by law, no press release,
publicity statement or other public notice related to this Agreement or the
transactions contemplated hereby, or other announcements to the employees,
customers or suppliers of Seller shall be issued prior to Closing without the
joint approval of Purchaser and Seller.  Purchaser and Seller shall cooperate
to prepare a joint press release to be issued at the time of the signing of
this Agreement and on the Closing Date.  No other public announcement related
to this Agreement or the transactions contemplated hereby shall be made by
either party prior to or at Closing, except as required by law or any listing
or trading agreement concerning its publicly-traded securities, in which event
the disclosing party will use reasonable efforts to advise the other party
prior to making the disclosure.

     11.2 EXPENSES.  Except as specifically set forth in Sections 11.9 and
11.11 below, each party shall pay all of its expenses in connection with the
negotiation of this Agreement, the performance of its obligations hereunder and
the consummation of the transactions contemplated by this Agreement.

     11.3 FURTHER ASSURANCES.  At any time after the Closing Date, Seller and
Parent will, at Purchaser's request and cost, promptly execute, acknowledge and
deliver any other assurances or documents requested by Purchaser in order to
complete the conveyances and transfers of the Purchased Assets contemplated
herein or otherwise necessary to provide Purchaser with the benefits
contemplated hereby.

     11.4 RESERVED.

     11.5 NON-COMPETE; NON-SOLICITATION.

          (a) In consideration of the payment of the amount of the Purchase
     Price allocated by the parties for this "Covenant Not To Compete" as
     described in Sections 2.1 and 2.2 above and as a significant and material
     inducement for Purchaser to enter into this Agreement, for a period of
     seven (7) years after the Closing (the "Non-Competition Period"),  each of
     Seller and Parent and their respective affiliates, successors and assigns
     hereby agrees to and shall, and agrees to and shall cause their respective
     directors (who are employees of Seller) and officers (while employed by
     Seller), affiliates, successors and assigns to refrain from, directly or
     indirectly:

              (i)   owning, managing, operating, controlling or otherwise being
     affiliated with any Person or business that is engaged in any of the
     Noncompetition Businesses (as defined below) or in the mining, processing,
     distributing and/or selling of attapulgite clay, porters creek clay,
     Montmorillonite (as defined in Section 11.5(g) below), non-swelling
     calcium bentonite and/or diatomite (collectively, the "Noncompete
     Minerals") in connection with any of the following businesses and
     products:  (A) Traditional Litter Products (as defined in Section 11.5(e)
     below); (B) oil/grease absorbent products; (C) agricultural/agronomic
     products (including clay carriers for insecticides, herbicides and
     pesticides); (D) feed additive products including, but not limited to,
     anti-caking agents, flowability aids and pellet binders; and (E) turf/soil
     additives (such businesses and products listed in items (A) through (E)
     above are collectively referred to herein as the "Noncompetition
     Businesses"), in each case anywhere within the United States and Canada
     (the "Geographical Area"); provided, that nothing herein shall limit the
     ability of Seller to (1) sell Traditional Litter Products to Permitted
     Accounts (as defined in Section 11.5(d) below) and (2) use clay
     specification material for colored flecks in Scoopable Litter Products (as
     defined in Section 11.5(f) below), in each case of clauses (1) and (2)
     above with product supplied under the Traditional Supply Contract or
     otherwise supplied by Purchaser;

              (ii)  making sales of the Noncompete Minerals for use in the
     Noncompetition Businesses to any Person or entity (except for Permitted
     Accounts) that was a customer of Seller at any time prior to the Closing
     Date;

              (iii) using or disclosing to others for any reason at any time,
     except as may be required by law, any trade secret or confidential
     information, if any, included in the Purchased Assets; or

              (iv)  selling or transferring any material portion of the assets 
     at the Paris Facility and not included within the Purchased Assets to any
     Person reasonably likely to (A) utilize such assets in the Noncompetition
     Businesses in the Geographical Area, or (B) sell or transfer such assets
     for use by any Person engaged in or reasonably likely to engage in the
     Noncompetition Business with such assets in the Geographical Area;
     provided, however, that if Seller elects to auction any such assets in a
     public auction, Seller may do so without restriction if it first gives
     fifteen (15) days advance written notice to Purchaser of the date, time
     and place of such auction and provides Purchaser both the opportunity to
     view and purchase such assets prior to the date of such auction and to
     participate in the aforesaid auction.

          (b) In the event that any court shall finally hold that the
     Non-Competition Period, Geographical Area or any other restriction stated
     in Section 11.5(a) above constitutes an unreasonable restriction upon any
     of Seller, Parent or their respective affiliates, successors, assigns,
     directors or officers, as the case may be, Seller and Parent, for
     themselves and their respective affiliates, successors, assigns, directors
     and officers, hereby expressly agree that the provisions of Section
     11.5(a) shall not be rendered void, but shall apply as to such time and to
     such extent as such court may judicially determine or indicate constitutes
     a reasonable restriction under the circumstances involved.  The parties
     hereto desire that such provisions shall be enforced as if they were drawn
     to the extent providing the maximum legal protection to Purchaser.

          (c) Seller and Parent recognize and affirm that in the event of
     breach of any of the provisions of this Section 11.5, money damages would
     be inadequate and Purchaser would have no adequate remedy at law.
     Accordingly, Seller and Parent agree that Purchaser shall have the right,
     in addition to any other rights and remedies existing in its favor, to
     enforce its rights and Seller's and Parent's obligations under this
     Section 11.5 not only by an action or actions for damages, but also by an
     action or actions for specific performance, injunction and/or other
     equitable relief without posting any bond or security to enforce or
     prevent any violations, whether anticipatory, continuing or future, of the
     provisions of this Section 11.5, including, without limitation, the
     extension of the Non-Competition Period by a period equal to (i) the
     length of the violation of this Section 11.5 plus (ii) the length of any
     court proceedings necessary to stop such violation.  In the event of a
     breach or violation by Seller of any of the provisions of this Section
     11.5, the running of the Non-Competition Period, but not of Seller's
     obligations under this Section 11.5, shall be tolled during the period
     during which such occurrence of any breach or violation is investigated
     and during the continuance of any actual breach or violation.  Seller and
     Parent (i) acknowledge and agree that Purchaser is acquiring from Seller
     hereunder, as part of the Purchased Assets, among other things, the
     Intellectual Property, and certain confidential and proprietary
     information and goodwill, which is unique and specific to the Purchased
     Assets, and that Purchaser is entitled to the relief provided under this
     Section 11.5 notwithstanding Seller's retention of ownership of the
     Excluded Assets, including any similar information or goodwill associated
     therewith; and (ii) waive any claim that Purchaser lacks a legitimate
     property interest in the Purchased Assets, including, without limitation,
     the Intellectual Property, which is entitled to the protection afforded by
     the provisions of this Section 11.5, due to Seller's continued ownership
     of the Excluded Assets, including any information or goodwill associated
     therewith.

          (d) The term "Permitted Accounts" means those customers who are
     primarily engaged in the sale of pet products for wholesale or retail
     distribution and customers selling pet products through "farm and fleet"
     stores, including, but not limited to, the customers listed on Schedule
     11.5.

          (e) The term "Traditional Litter Products" means coarse/traditional
     cat litter made from the Noncompetition Minerals excluding  Scoopable
     Litter Products (as defined below), paper/kaolin, cedar, zeolite, wood
     chips, wheat and any or all other similar products sold in retail stores
     on or prior to the Closing Date.

          (f) Notwithstanding anything to the contrary herein, the provisions
     of this Section 11.5 shall not limit or restrict in any manner Seller,
     Parent or any of their respective affiliates, successors, assigns,
     officers or directors from, directly or indirectly, engaging in any aspect
     of (i) the Scoopable Litter Products business, (ii) providing
     transportation services with respect to any products or materials of any

     bentonite.

     11.6 SPECIFIC PERFORMANCE. Seller and Parent acknowledge that the
Purchased Assets are unique and recognize and affirm that in the event of a
breach of this Agreement by Seller or Parent, money damages would be inadequate
and Purchaser would have no adequate remedy at law.  Accordingly, Seller and
Parent agree that Purchaser shall have the right, in addition to any other
rights and remedies existing in its favor, to enforce its rights and Seller's
and Parent's obligations hereunder not only by an action or actions for damages
but also by an action or actions for specific performance, injunction and/or
other equitable relief, without posting any bond or security.

     11.7 CERTAIN COMMUNICATIONS.  All notices and other communications
relating to the Assumed Liabilities received by Seller at any time after the
Closing Date shall be promptly forwarded to Purchaser.

     11.8 BEST EFFORTS TO CONSUMMATE CLOSING TRANSACTIONS.  On the terms and
subject to the conditions contained in this Agreement, each of Seller, Parent
and Purchaser each agree to use its best efforts to take, or to cause to be
taken, all reasonable actions, and to do, or to cause to be done, all
reasonable things, necessary, proper or advisable under applicable laws and
regulations to consummate, as soon as reasonably practicable, the Closing,
including the satisfaction of all conditions thereto set forth herein.  In
connection herewith, best efforts shall not require a party to commence
litigation against or acquire control of a third party, or to 

                                  Page -50-



<PAGE>   35
accelerate the payment of any indebtedness or scheduled payment, or to make
any payment to a third party to obtain a consent (other than payment of
Transfer Taxes to the extent required by Section 11.11 below).

     11.9  THIRD PARTY TERMINATION.  In recognition of the efforts, expenses,
and other opportunities foregone by Purchaser while structuring the
transactions contemplated hereby, the parties agree that if prior to the
earlier to occur of (a) the Closing hereunder, or (b) December 31, 1998, any
Person or entity, other than Purchaser, or a subsidiary or affiliate of
Purchaser, shall directly or indirectly, or acting through one or more
intermediaries or affiliates, (i) enter into an agreement or understanding with
Seller or Parent relating to the acquisition by such Person of the Purchased
Assets or stock of Seller (whether by asset purchase, stock purchase, merger or
otherwise) or (ii) publicly announce or commence a tender or exchange offer
with the intent to accomplish any of the foregoing, which offer the Board of
Directors of Seller does not reject, then, upon demand, Seller and Parent,
jointly and severally, shall pay to Purchaser a termination fee, in cash, of
$875,000 plus the actual amount of out-of-pocket costs incurred by Purchaser in
pursuing the transactions contemplated hereby including, without limitation,
legal fees, costs and expenses; environmental, health and safety audit costs;
accountant's fees, costs and expenses; and fees for governmental filings
(collectively, the "Termination Fee").  The Termination Fee shall be deemed
neither Purchaser's exclusive remedy hereunder nor liquidated damages and shall
instead be in addition to any other rights and remedies of Purchaser for breach
of this Agreement, whether in equity or at law.  Notwithstanding the foregoing,
the provisions of this Section 11.9 shall survive the termination of this
Agreement for any reason and remain applicable except for proper termination of
this Agreement (A) by Seller pursuant to Section 10.1(b) or Section 10.1(d),
(B) by Purchaser pursuant to Section 10.1(c) or (C) by both parties pursuant to
Section 10.1(a).

     11.10 EMPLOYEES OF SELLER.

           (a) Prior to the Closing Date, Purchaser will  provide Seller with a
     list of the Hourly Employees and the Salaried Employees to whom Purchaser
     agrees to offer employment on the day following the Closing Date.  Any
     individual to whom Purchaser offers employment, and who accepts such
     offer, shall become an employee of Purchaser on the day following the
     Closing Date, except that any individual who is on long-term or short-term
     disability leave as of the Closing Date shall not become an employee of
     Purchaser prior to the first day such individual actually reports for work
     with Purchaser.

           (b) Upon the occurrence of the Closing, Purchaser agrees to offer
     employment to substantially all of the employees of Seller at the Mounds
     Facility and shall maintain such employment for a period of at least sixty
     (60) days following the Closing Date (except for such employees who are
     terminated for cause within such period).  Purchaser shall have the
     absolute right to establish all terms and conditions of employment,
     including wages, benefits, and benefit plans, for any employees of Seller
     to whom it chooses to make an offer of employment to be employed by
     Purchaser.  Further, it is expressly agreed that Purchaser is not bound by
     any previous or existing collective bargaining agreement which may be in
     existence between Seller and any representatives of Seller's employees,
     nor is Purchaser bound to assume, implement or continue any wages, terms
     and conditions of employment, benefits or benefit plans which may
     currently exist for Seller's employees.  All such offers of employment 
     shall be on the terms and conditions established by Purchaser.  Seller 
     agrees not to discourage any such employees from accepting employment 
     with Purchaser.

     11.11 PAYMENT OF TRANSFER TAXES AND TAX FILINGS AND CERTAIN POST-CLOSING
AGREEMENTS.

           (a) Seller shall pay all of the transfer taxes imposed upon, or
     assessed upon or with respect to, the transfer of the Purchased Assets to
     Purchaser and any transfer taxes to effect any recording or filing with
     respect thereto (collectively, the "Transfer Taxes") and all recording
     costs, together up to the first One Hundred Thousand Dollars ($100,000) of
     such Transfer Taxes; thereafter, Purchaser shall pay all such Transfer
     Taxes and recording costs.  The party responsible for the payment thereof
     shall timely prepare and file any returns or other filings related to such
     Transfer Taxes, including any claim for exemption or exclusion from the
     application or imposition of any Transfer Taxes, shall pay such Transfer
     Taxes when due and shall promptly following the filing thereof furnish a
     copy of such return or other filing and a copy of a receipt showing
     payment of any such Transfer Taxes to the other party.

           (b) Each party agrees to furnish or cause to be furnished to the
     others, upon request, as promptly as practicable, such information and
     assistance at the requesting party's cost relating to the Purchased Assets
     as is reasonably necessary for the filing of all Tax returns, including
     any claim for exemption or exclusion from the application or imposition of
     any Taxes or making of any election related to Taxes, the preparation for
     any audit by any taxing authority and the prosecution or defense of any
     claim, suit or proceeding relating to any Tax return.

           (c) The parties acknowledge that the Purchase Price will be allocated
     among the Assets in accordance with Section 2.2 of this Agreement.
     Purchaser and Seller agree that they shall each prepare and file IRS Form
     8594, as required by Section 1060 of the Code and the treasury regulations
     promulgated thereunder in a manner consistent with the foregoing
     allocation.

                                  Page -51-



<PAGE>   36
           (d) Seller shall deliver to Purchaser at or prior to the Closing an
     affidavit under penalties of perjury stating:  (1) its name, address, and
     taxpayer identification number and (ii) that it is not a "foreign person"
     within the meaning of Section 1445 of the Code.

           (e) Seller agrees that, on and after the Closing Date, it will
     cooperate with Purchaser to transfer right, title and interest in and to
     its telephone numbers at the Mounds Facility to Purchaser.  Purchaser
     agrees to pay all costs and expenses associated with such transfer.

     11.12 BULK SALES LAWS.  The parties hereto waive compliance with the
statutory provisions relating to the bulk sales and transfers, if applicable.

     11.13 CASUALTY.  In the event of any casualty or damage to the Purchased
Assets which occurs prior to the Closing Date for which the cost to repair such
casualty or damage is less than Two Hundred Fifty Thousand Dollars ($250,000),
Purchaser shall take an assignment at Closing from Seller of all of Seller's
right, title and interest in insurance proceeds payable with respect to such
casualty or damage which can then be used by Purchaser to repair such casualty
or damage, plus an amount in cash (payable by Seller to Purchaser at Closing)
equal to the deductible under any such insurance policies and, thereupon, there
shall be no adjustment of the Purchase Price and this Agreement shall remain in
full force and effect.  If, on the other hand, the cost to repair such casualty
or damage exceeds such amount, Purchaser may elect to either:  (a) terminate
this Agreement by written notice to Seller without any further recourse against
Seller; or (b) consummate the transactions contemplated herein without
adjustment of the Purchase Price and take an assignment at Closing from Seller
of all of Seller's right, title and interest in insurance proceeds plus an
amount in cash (payable by Seller to Purchaser at Closing) equal to the
deductible under any such insurance policies.

           OIL-DRI'S BOARD APPROVES ACQUISITION, STOCK REPURCHASE
                              AND CASH DIVIDEND


CHICAGO -- March 12, 1998 -- Oil-Dri Corporation of America (NYSE-ODC)
announced today that its Board of Directors has approved the pending
acquisition of the Fuller's Earth absorbent business of American Colloid, a
subsidiary of AMCOL International.

The Board also authorized the repurchase of a block of 342,000 shares from
director, Robert D. Jaffee. That purchase has exhausted the company's
authorizations for further stock repurchases at present.

"I am reluctant to sell my Oil-Dri stock," said Robert Jaffee.  "I am wholly
confident that the business is being well managed and it appears to have
excellent prospects, but I must face the realities of estate planning and the
interests of my family."

Richard M. Jaffee, Oil-Dri's chairman, commented,  "the Board believes that
purchase of this block of stock comes at a very good time for Oil-Dri. There
are a lot of positive events driving the business and it would be difficult
to find a block this large at the discounted rate of $15.00 per share which
we have agreed upon."

Since the May, 1994 authorization from the board, Oil-Dri has repurchased
more than a million shares of common stock and therefore reduced shares
outstanding by 15%.

The Board also declared a dividend of $0.08 per share for the Company's
Common Stock and $0.06 per share for the company's Class B stock. The
dividends are payable on June 12, 1998 to shareholders of record at the close
of business on May 15, 1998.

This release contains certain forward-looking statements regarding the
company's expected performance for future periods and actual results for such
periods may materially differ. Such forward-looking statements are subject to
uncertainties, which include, but are not limited to, competitive factors in
the grocery, mass merchandiser and club segments of the consumer market; the
level of success of new products; changes in planting activity and overall
agricultural demand; changes in market conditions and the overall economy,
and other factors detailed from time to time in the company's annual report
and other reports filed with the Securities and Exchange Commission.

Oil-Dri Corporation of America is a leader in developing, manufacturing and
marketing products and for pet care, industrial, environmental, agricultural,
and fluids purification markets.
